If you have a Wandboard revB1 and are willing to test the resulting dtb
file, I can provide patches with the required changes to avoid conflicting
definitions with rev D1. I can test rev C1 and D1. Then if we're happy with
the results, I'll try to upstream them.

I'll will send you a direct download link from dropbox as a personal email
message. I've prepared a rootfs for Ubuntu Mate 17.04 with etnaviv
pre-installed and configured. It shows all issues I've been talking about,
the MMU faults as well as the unexpected screen blanking. Please remember
that imx6q will work fine, these issues only occur on imx6qp. I didn't send
a complete SD card image, as your hardware is different...
